POI Word 模板 文字 图片 替换 验证通过必须3.7版本
实验环境：POI3.7+Word2007
Word模板：
替换后效果：
代码：
1、入口文件
Java代码
- public class Test {
- public static void main(String[] args) throws Exception {
- Map<String, Object> param = new HashMap<String, Object>();
- param.put("${name}", "huangqiqing");
- param.put("${zhuanye}", "信息管理与信息系统");
- param.put("${sex}", "男");
- param.put("${school_name}", "山东财经大学");
- param.put("${date}", new Date().toString());
- Map<String,Object> header = new HashMap<String, Object>();
- header.put("width", 100);
- header.put("height", 150);
- header.put("type", "jpg");
- header.put("content", WordUtil.inputStream2ByteArray(new FileInputStream("c:\\new.jpg"), true));
- param.put("${header}",header);
- Map<String,Object> twocode = new HashMap<String, Object>();
- twocode.put("width", 100);
- twocode.put("height", 100);
- twocode.put("type", "png");
- twocode.put("content", ZxingEncoderHandler.getTwoCodeByteArray("测试二维码,huangqiqing", 100,100));
- param.put("${twocode}",twocode);
- CustomXWPFDocument doc = WordUtil.generateWord(param, "c:\\1.docx");
- FileOutputStream fopts = new FileOutputStream("c:/2.docx");
- doc.write(fopts);
- fopts.close();
- }
- }
2、封装的工具类WordUtil.java
Java代码

3、重写的类 CustomXWPFDocument
